In Firefox 4 you can do this:

Components.untils.import("resource://gre/modules/Services.jsm");
Services.prefs.setCharPref("intl.accept_languages", "fr");

Note: this only works for ASCII preferences. See nsIPrefBranch for more details.

In previous versions of firefox you need to obtain the preference service manually, like this:

var rootPrefs = Components.classes['@mozilla.org/preferences-service;1'].getService(Components.interfaces.nsIPrefBranch);
rootPrefs.setCharPref("intl.accept_languages", "fr");

Alternatively if you're writing an extension then you can include a default preference file which will override the installation default, although it won't override a user set preference.
